To all whom, it may 0mm; I

Be it known that I, ALTEN S. MILLER, a

citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Packing Materials, of which the following is a speci-' of the gas or oil thereon. My present pack ing has the advantage ofkeeping the oints permanently tight. Of course, it will be understood that the joints to which I refer are not the screw-threaded joints formed Where one pipe merely screw connects with another, but the type of joint made by slipping the end of one pipe into the enlarged.

end of another pipe, or by bringing together .the ends of two plpes of uniform size and putting a sleeve over the two pipe ends. llhere 1s necessarlly a. cons derable internal space between the enlarged end of the one:

pipe and the outside of the end of the other is inserted to make the joint tight and it is the object of my invention to produce a packing which will effectively accomplish this.

My improved packing, consists of a packing material preferably a fibrous material such as jute, hemp, cotton, or wool, etc., but preferably jute on account of its cheapness,-with which has been incorporated The finished form of packing is prefa loosely twisted or braided rope of soap.

era ly the soap incorporated fibrous material adapted to be laid into the joint, coil upon coil, and then rammed or otherwise forced hard into place, where it is held by a gland of lead, iron or other material, with the result that the packing keeps the finished joint perfectly tight because the soap fills ;all the pores and spaces, and furthermore does this, ermanently because it is not acted .upon by the ingredients of the gas or oil in the pipe. 7

There are anumber of Ways of incorporating the soap .with the packing material.

"To state some of them:-the packing material whether in the form of rope or other- Wise may be dipped into the hot or melted soa dram and dry when it will be ready for use; or to secure still more thorough incorporation of the soa with the packing material, it may be dipped into the soap or otherwise -'impregnated therewith in small portions or strands, which are then aggregated to make up the mass of the packing or in the case of strands, they may be twisted together or braided to form the finished rope-packing, this being the preferred form as already described.

' The soap I use may or crude soap.

What I claim is 1. A packing for, the joints of gas pipes, compris ng a body of fibrous material that is unaffected by gas ,-and a filling composed wholly of soap that is insoluble in and unbe the-ordinary clieap affected by gas.

2., A packing for the joints of gas ipes, com rising a body of vegetable fiber t at is una ected by gas, and'a filling composed wholly of soap that is insoluble in and unaffected by gas, said soap filling the interstices and spaces in and around the fibrous body. Y Y i 3. A packing suitable for the joints of gas and oil pipes and vessels, consistingof a fibrous packing materialhaving soap mechanically carried thereby, so that when the packing 1s in place, the pores and spaces are filled with soap which is insoluble to the gas and oil contained in the pipe or vessel. In testimony whereofI atfix my signature in presence of two witnesses.
